Application med October 5, 1920. Serial No. 414,844.

To all whom t may cof/wem:

Be` it known that I, ARTHUR POWELL, subject of the King of Great Britainand Ireland, and resident of Cobridge, Stokeon-Trent, in the county ofStaord, England, manager, have invented certain new and usefulImprovements in or Ap licable to Shoe Heels, of which the following is aspecification."

My invention relates to improvements in' or applicable to the heels ofboots, shoes and other footwear and has particular reference to the typeof heels having detachable rubber or composition pads, the object beingimproved means for enabling the rubber or composition pad to be readilyconnected to the heel proper ofthe boot or other footwear and betransferred or renewed when desired, a further object being means forpreventing the displacement of the rubber or composition pad duringvwear.

My invention consists essentially in a rubber or composition pad havinga projection, tongue, or raise portion thereon provided with an inclinedprojecting edge toengage a correspondingly shaped groove, bevelled orundercut edge round an open slot in a metal late fixed on the heelproper of the boot, s oe or other footwear, the said open slotted metalplate having holes or recesses therein to accommodate projections formedon the rubber or composition padto prevent the displacement thereof whenin use.

My invention will be fully described with reference to the accompanyingdrawings in which,

lFig. 1 is an elevation of part of a gentlemans boot having y improveddetachableheel padapplied thereto, j

Fig. 2 is an elevation of the heel, shown at Fi 1, removed 'from theboot Without the detac able rubber or composition pad,

Fig.v 3 is a plan of F i 2. Fi 4 is a lan of a lIshaped metal plate whicis fixe to the heel proper of the boot or other footwear and enables therubber pad to be detachably secured in position and readily removed asdesired,

lFigui/9 is a back view of the heel of a boot -with the detachablerubber or composition Fig. 12 is a Similar View to Fig. 1 butillustrating a part ofa ladys boot having the detachable pad,

Fig. 13 is a back view of Fig. 12,

Fig. 14 is a view of the inside of the vFi 15 is l, an inverted plan ofthe ladys heel illustrated at Fig. 1,2,

Fig. 16 is a plan of a U shaped metal plate which is attached to theladys heel to carry the detachable rubber or composition pad,

Fig. 17 is a cross section through line E--F of Fig. 16, and t Fig. 18is a view of the complete heel as seen from the inside thereof, thesides of the rubber or composition pad being pressed downwards andassuming the position `when the pad is being removed from the U shapedmetal plate fixed on the heel proper.

In these figures a is the heel proper and c the upper portion of theboot or other foot wear, these being of the usual well knownconstruction.

Accordin to my said invention I .employ a lU s aped metal plate k (seeplan ig. 4) which is secured to the heel a of the boot or other footwearby screws m passing through countersunk holes n. The said plate k ispreferably constructed of alumin- -ium for lightness and has a slot dopen at its inside m as shown at Fig. 4, the edge of the said slot dbeing inclined or bevelled so that when in positlon on the boot heel itforms an undercut groove e2 extendin all round the open slot al for theedge f2 o the' projection or raised portion f of the ad to slide in. Tofurther assist in fixing t e detachable rubber pad b and to preventdislacement thereof during wear, i I employ iioles h2 in the U shapedmetal plate k to accommodate projections g (Figs' and 7) formed on therubber or composition pad b. The said holes h2 form recesses when theplate k is on the boot heel and if desired iii? the arrow Y (Fig. 4)into the open slot d to engage the inclined edge e2 of the U shape metalplate, the projections g on the rubber pad then engaging the holes orrecessles if? in the metal plate.

in some cases a projection j on the back of the rubber pad b (shown`dotted at Fig. 6)

lll

material to strengthen the raised portion or tonxe f.

'l e outer orv tread portion of the rubber or composition pad b isroughened in any suitable way to prevent slipping.`

Rubber or composition pads of various thicknesses ma'y be moulded orshapedto y engage the metal U shaped plate when se- `cured to a ladyshigh .heel by which means the dheight of the heels may be varied asdesire To facilitate easy insertion, the rubber or composition pad b isgripped by the ngers at its two sides (see F 1g. 18) whilst theedge f2of the tongue f of the pad is sliding into the undercut groove e2 of theU shaped plate, the projections g on the pad taking into the :temeerrecesses h2 of theA metal plate immediately the sides of the pad arereleased., To remove the rubber or composition pad b the sides thereofare pressed until the projec- Vtions g clear their recesses h2 in theplate k when the rubber pad is slid out of the open slot d. This enablesthe pad to be transerred from one boot to the other during Wear or a newpad to be substituted when member having apertures, the walls of whichare inclined iongitudinally of the member for a distance at the rearedges of said apertures and terminate in walls at right angles to thelength of the said member, in combination with a complementary pad orrubber lift having raised portions with beveled sides and end, and studsositioned at the sides of the beveled sides ci) the pad, the said studshavingy inclined ed es conforming generally to the contour of t e wallsof the apertures of the first mentioned member and adapted to enter thesaid apertures.

in testimony whereof i have hereunto set my hand in the presence of twowitnesses.

ARTHUR POWELL.
